I have a VR 93 FD. I just found out via my turbo boost gauge that my second turbo is not kicking in after the first one engages. I know that the pattern should be close to 10-8-10 but it's like 10-8-4. everything is stock except dp, aluminum ast. I'm checking the vacuum lines but are there any other possibilities? I could take it to Ivan here in Sunnyvale but i'm just trying to prevent another kick in the wallet. I appreciate all the help. Thanks. Em

 

sounds like the same problem i have.....but mines in the body shop...so i havnt had a chance to see the actual boost numbers or checked the hoses

 

oh yea...if you search, my thread about it was called 'glowing turbo?' or something like that....might help you out a lil

 

check your turbo control acutator

i have an extra if ya need one
